Absolutely correct, Honest Roberts. Silly brothers Einsteinians claim
that the pole is "trapped IN A COMPRESSED STATE inside the barn":

http://math.ucr.edu/home/baez/physics/Relativity/SR/barn_pole.html
"These are the props. You own a barn, 40m long, with automatic doors
at either end, that can be opened and closed simultaneously by a
switch. You also have a pole, 80m long, which of course won't fit in
the barn. (...) If it does not explode under the strain and it is
sufficiently elastic it will come to rest and start to spring back to
its natural shape but since it is too big for the barn the other end
is now going to crash into the back door and the rod will be trapped
IN A COMPRESSED STATE inside the barn."

Parabola Volume 35, Issue 1 (1999), LENGTH AND RELATIVITY by John
Steele:
"Suppose you want to fit a 20m pole into a 10m barn. (...) Hence in
both frames of reference, the pole fits inside the barn (and will
presumably shatter when the doors are closed)."

...but clever brothers Einsteinians (you are among them, Honest
Roberts) know that there can be no compression, shattering etc. If
silly brothers could look at the trapped pole from the correct angle,
they would see no compression, shattering etc. Am I right, Honest
Roberts?

Bwahahahaha!
Let's Humpty Roberts squirm.
And what is really funny is that according to the arithmetic the pole
shrinks when it comes to rest.
